Best pins for sensors and relays



  • Hi,

    I have a project with:

    • 1 DS18B20 sensor (3 wires)
    • 2 water flow meters (3 wires)
    • 2 relays

    I will probably use the M5 PLC module to prototype the circuit.

    What is for you the best pins to use for sensors and relays?

    Thanks
